Hi,
Is there a way to delay a connection for some time?
Depending how you want your delay to be used, you might be able
to use it with TCP rules, something like this :
acl acl_to_delay <something>
tcp-request content accept if !acl_to_delay
tcp-request content accept if WAIT_END
I've done a clone of tarpit (with bindings and reqidelay), but it
doesn't want to work
if (txn->flags & TX_CLDELAY) {
/* wipe the request out so that we can drop the
connection early
* if the client closes first.
*/
buffer_write_dis(req);
req->analysers |= AN_REQ_HTTP_DELAY;
req->analyse_exp = tick_add_ifset(now_ms,
s->be->timeout.delay);
if (!req->analyse_exp)
req->analyse_exp = tick_add(now_ms, 0);
}
int http_process_delay(struct session *s, struct buffer *req)
{
struct http_txn *txn = &s->txn;
if ((req->flags & (BF_SHUTR|BF_READ_ERROR)) == 0 &&
!tick_is_expired(req->analyse_exp, now_ms))
You have to add that before return because process_session()
will enable it first :
buffer_write_dis(req);
return 0;
if (req->flags != BF_READ_ERROR)
buffer_write_ena(req);
return 1;
And here since the delay is expired, you have to remove your
analyser :
req->analysers &= ~AN_REQ_HTTP_DELAY;
return 0;
}
Upon match it doesn't delay, it just waits until 503 error...
Probably because of the missing flush of the analyser bit (I think).
Seems like I've done it wrong somewhere with buffer_write_dis|ena(req)?
In part :-)
Also, I suggest that you do that with 1.4-dev1, you may find it
much easier and you will be able to duplicate code from smaller
functions. Also one of the advantages is that multiple analysers
may be enabled at once.
